i brought a 3" downpipe and decat off ebay was a cheapy one took it to the garage yesterday where i helped fitting it.
the flanges etc. are perfect fit the only thing is we couldnt get it to fit as the rear axle is in the way, im finding it very hard to find parts for my car as its the a3 1.8t quattro it has the same flange as the a3 but same layout as the s3 does anyone know where i can get downpipe and decat that will fit? or should i buy a s3 downpipe and decat and cut the flange off and weld the flange for the a3 onto it?
